Olivier Giroud and Timo Werner scored in a nine-minute first-half spell to give Chelsea a 2-0 win over Newcastle United that takes them up to fourth in the table.
Giroud, an early substitute for the injured Tammy Abraham, was on hand to score the opener after a Werner cross was diverted into his path by Magpies goalkeeper Karl Darlow.
And then Werner scored his first Premier League goal in exactly 1,000 minutes when Mason Mount's corner found its way to him at the far post.
Goalkeeper Kepa Arrizabalaga, playing his first league match since October, had to save from Jonjo Shelvey and Joe Willock after the break as Newcastle responded.
But at the other end, Darlow denied Marcos Alonso and Reece James.
Chelsea are now ahead of Liverpool and West Ham on 42 points, four behind Manchester United and Leicester.
Newcastle stay 17th on 25 points, seven ahead of Fulham.
